URL is the URL of the Authorization that must be completed

Identifier is the DNS name to be validated as part of this authorization

Wildcard will be true if this authorization is for a wildcard DNS name. If this is true, the identifier will be the non-wildcard version of the DNS name. For example, if ‘*.example.com’ is the DNS name being validated, this field will be ‘true’ and the ‘identifier’ field will be ‘example.com’.

InitialState is the initial state of the ACME authorization when first fetched from the ACME server. If an Authorization is already ‘valid’, the Order controller will not create a Challenge resource for the authorization. This will occur when working with an ACME server that enables ‘authz reuse’ (such as Let’s Encrypt’s production endpoint). If not set and ‘identifier’ is set, the state is assumed to be pending and a Challenge will be created.

Challenges specifies the challenge types offered by the ACME server. One of these challenge types will be selected when validating the DNS name and an appropriate Challenge resource will be created to perform the ACME challenge process.

URL is the URL of this challenge. It can be used to retrieve additional metadata about the Challenge from the ACME server.

Token is the token that must be presented for this challenge. This is used to compute the ‘key’ that must also be presented.

Type is the type of challenge being offered, e.g. ‘http-01’, ‘dns-01’, ‘tls-sni-01’, etc. This is the raw value retrieved from the ACME server. Only ‘http-01’ and ‘dns-01’ are supported by cert-manager, other values will be ignored.

Selector selects a set of DNSNames on the Certificate resource that should be solved using this challenge solver. If not specified, the solver will be treated as the ‘default’ solver with the lowest priority, i.e. if any other solver has a more specific match, it will be used instead.

Configures cert-manager to attempt to complete authorizations by performing the HTTP01 challenge flow. It is not possible to obtain certificates for wildcard domain names (e.g. *.example.com) using the HTTP01 challenge mechanism.

Configures cert-manager to attempt to complete authorizations by performing the DNS01 challenge flow.

CNAMEStrategy configures how the DNS01 provider should handle CNAME records when found in DNS zones.

Configure an external webhook based DNS01 challenge solver to manage DNS01 challenge records.

The ingress based HTTP01 challenge solver will solve challenges by creating or modifying Ingress resources in order to route requests for ‘/.well-known/acme-challenge/XYZ’ to ‘challenge solver’ pods that are provisioned by cert-manager for each Challenge to be completed.

The Gateway API is a sig-network community API that models service networking in Kubernetes (https://gateway-api.sigs.k8s.io/). The Gateway solver will create HTTPRoutes with the specified labels in the same namespace as the challenge. This solver is experimental, and fields / behaviour may change in the future.

Optional service type for Kubernetes solver service. Supported values are NodePort or ClusterIP. If unset, defaults to NodePort.

Custom labels that will be applied to HTTPRoutes created by cert-manager while solving HTTP-01 challenges.

When solving an HTTP-01 challenge, cert-manager creates an HTTPRoute. cert-manager needs to know which parentRefs should be used when creating the HTTPRoute. Usually, the parentRef references a Gateway. See: https://gateway-api.sigs.k8s.io/api-types/httproute/#attaching-to-gateways

Optional service type for Kubernetes solver service. Supported values are NodePort or ClusterIP. If unset, defaults to NodePort.

This field configures the field ingressClassName on the created Ingress resources used to solve ACME challenges that use this challenge solver. This is the recommended way of configuring the ingress class. Only one of class, name or ingressClassName may be specified.

This field configures the annotation kubernetes.io/ingress.class when creating Ingress resources to solve ACME challenges that use this challenge solver. Only one of class, name or ingressClassName may be specified.

The name of the ingress resource that should have ACME challenge solving routes inserted into it in order to solve HTTP01 challenges. This is typically used in conjunction with ingress controllers like ingress-gce, which maintains a 1:1 mapping between external IPs and ingress resources. Only one of class, name or ingressClassName may be specified.

Optional pod template used to configure the ACME challenge solver pods used for HTTP01 challenges.

keyID is the ID of the CA key that the External Account is bound to.

keySecretRef is a Secret Key Selector referencing a data item in a Kubernetes Secret which holds the symmetric MAC key of the External Account Binding. The key is the index string that is paired with the key data in the Secret and should not be confused with the key data itself, or indeed with the External Account Binding keyID above. The secret key stored in the Secret must be un-padded, base64 URL encoded data.

Deprecated: keyAlgorithm field exists for historical compatibility reasons and should not be used. The algorithm is now hardcoded to HS256 in golang/x/crypto/acme.

Email is the email address to be associated with the ACME account. This field is optional, but it is strongly recommended to be set. It will be used to contact you in case of issues with your account or certificates, including expiry notification emails. This field may be updated after the account is initially registered.

Server is the URL used to access the ACME server’s ‘directory’ endpoint. For example, for Let’s Encrypt’s staging endpoint, you would use: “https://acme-staging-v02.api.letsencrypt.org/directory”. Only ACME v2 endpoints (i.e. RFC 8555) are supported.

PreferredChain is the chain to use if the ACME server outputs multiple. PreferredChain is no guarantee that this one gets delivered by the ACME endpoint. For example, for Let’s Encrypt’s DST crosssign you would use: “DST Root CA X3” or “ISRG Root X1” for the newer Let’s Encrypt root CA. This value picks the first certificate bundle in the ACME alternative chains that has a certificate with this value as its issuer’s CN

Base64-encoded bundle of PEM CAs which can be used to validate the certificate chain presented by the ACME server. Mutually exclusive with SkipTLSVerify; prefer using CABundle to prevent various kinds of security vulnerabilities. If CABundle and SkipTLSVerify are unset, the system certificate bundle inside the container is used to validate the TLS connection.

INSECURE: Enables or disables validation of the ACME server TLS certificate. If true, requests to the ACME server will not have the TLS certificate chain validated. Mutually exclusive with CABundle; prefer using CABundle to prevent various kinds of security vulnerabilities. Only enable this option in development environments. If CABundle and SkipTLSVerify are unset, the system certificate bundle inside the container is used to validate the TLS connection. Defaults to false.

ExternalAccountBinding is a reference to a CA external account of the ACME server. If set, upon registration cert-manager will attempt to associate the given external account credentials with the registered ACME account.

PrivateKey is the name of a Kubernetes Secret resource that will be used to store the automatically generated ACME account private key. Optionally, a key may be specified to select a specific entry within the named Secret resource. If key is not specified, a default of tls.key will be used.

Solvers is a list of challenge solvers that will be used to solve ACME challenges for the matching domains. Solver configurations must be provided in order to obtain certificates from an ACME server. For more information, see: https://cert-manager.io/docs/configuration/acme/

Enables or disables generating a new ACME account key. If true, the Issuer resource will not request a new account but will expect the account key to be supplied via an existing secret. If false, the cert-manager system will generate a new ACME account key for the Issuer. Defaults to false.

Enables requesting a Not After date on certificates that matches the duration of the certificate. This is not supported by all ACME servers like Let’s Encrypt. If set to true when the ACME server does not support it it will create an error on the Order. Defaults to false.

A label selector that is used to refine the set of certificate’s that this challenge solver will apply to.

List of DNSNames that this solver will be used to solve. If specified and a match is found, a dnsNames selector will take precedence over a dnsZones selector. If multiple solvers match with the same dnsNames value, the solver with the most matching labels in matchLabels will be selected. If neither has more matches, the solver defined earlier in the list will be selected.

List of DNSZones that this solver will be used to solve. The most specific DNS zone match specified here will take precedence over other DNS zone matches, so a solver specifying sys.example.com will be selected over one specifying example.com for the domain www.sys.example.com. If multiple solvers match with the same dnsZones value, the solver with the most matching labels in matchLabels will be selected. If neither has more matches, the solver defined earlier in the list will be selected.

A condition added to Certificate resources when an issuance is required. This condition will be automatically added and set to true if: * No keypair data exists in the target Secret * The data stored in the Secret cannot be decoded * The private key and certificate do not have matching public keys * If a CertificateRequest for the current revision exists and the certificate data stored in the Secret does not match the status.certificate on the CertificateRequest. * If no CertificateRequest resource exists for the current revision, the options on the Certificate resource are compared against the X.509 data in the Secret, similar to what’s done in earlier versions. If there is a mismatch, an issuance is triggered. This condition may also be added by external API consumers to trigger a re-issuance manually for any other reason.

It will be removed by the ‘issuing’ controller upon completing issuance.

List of status conditions to indicate the status of a CertificateRequest. Known condition types are Ready, InvalidRequest, Approved and Denied.

The PEM encoded X.509 certificate resulting from the certificate signing request. If not set, the CertificateRequest has either not been completed or has failed. More information on failure can be found by checking the conditions field.

The PEM encoded X.509 certificate of the signer, also known as the CA (Certificate Authority). This is set on a best-effort basis by different issuers. If not set, the CA is assumed to be unknown/not available.

FailureTime stores the time that this CertificateRequest failed. This is used to influence garbage collection and back-off.

Annotations is a key value map to be copied to the target Kubernetes Secret.

Labels is a key value map to be copied to the target Kubernetes Secret.

Requested set of X509 certificate subject attributes. More info: https://datatracker.ietf.org/doc/html/rfc5280#section-4.1.2.6

The common name attribute is specified separately in the commonName field. Cannot be set if the literalSubject field is set.

Requested X.509 certificate subject, represented using the LDAP “String Representation of a Distinguished Name” [1]. Important: the LDAP string format also specifies the order of the attributes in the subject, this is important when issuing certs for LDAP authentication. Example: CN=foo,DC=corp,DC=example,DC=com More info [1]: https://datatracker.ietf.org/doc/html/rfc4514 More info: https://github.com/cert-manager/cert-manager/issues/3203 More info: https://github.com/cert-manager/cert-manager/issues/4424

Cannot be set if the subject or commonName field is set. This is an Alpha Feature and is only enabled with the --feature-gates=LiteralCertificateSubject=true option set on both the controller and webhook components.

Requested common name X509 certificate subject attribute. More info: https://datatracker.ietf.org/doc/html/rfc5280#section-4.1.2.6 NOTE: TLS clients will ignore this value when any subject alternative name is set (see https://tools.ietf.org/html/rfc6125#section-6.4.4).

Should have a length of 64 characters or fewer to avoid generating invalid CSRs. Cannot be set if the literalSubject field is set.

Requested ‘duration’ (i.e. lifetime) of the Certificate. Note that the issuer may choose to ignore the requested duration, just like any other requested attribute.

If unset, this defaults to 90 days. Minimum accepted duration is 1 hour. Value must be in units accepted by Go time.ParseDuration https://golang.org/pkg/time/#ParseDuration.

How long before the currently issued certificate’s expiry cert-manager should renew the certificate. For example, if a certificate is valid for 60 minutes, and renewBefore=10m, cert-manager will begin to attempt to renew the certificate 50 minutes after it was issued (i.e. when there are 10 minutes remaining until the certificate is no longer valid).

NOTE: The actual lifetime of the issued certificate is used to determine the renewal time. If an issuer returns a certificate with a different lifetime than the one requested, cert-manager will use the lifetime of the issued certificate.

If unset, this defaults to ¹⁄₃ of the issued certificate’s lifetime. Minimum accepted value is 5 minutes. Value must be in units accepted by Go time.ParseDuration https://golang.org/pkg/time/#ParseDuration.

Requested DNS subject alternative names.

Requested IP address subject alternative names.

Requested URI subject alternative names.

otherNames is an escape hatch for SAN that allows any type. We currently restrict the support to string like otherNames, cf RFC 5280 p 37 Any UTF8 String valued otherName can be passed with by setting the keys oid: x.x.x.x and UTF8Value: somevalue for otherName. Most commonly this would be UPN set with oid: 1.3.6.1.4.1.311.20.2.3 You should ensure that any OID passed is valid for the UTF8String type as we do not explicitly validate this.

Requested email subject alternative names.

Name of the Secret resource that will be automatically created and managed by this Certificate resource. It will be populated with a private key and certificate, signed by the denoted issuer. The Secret resource lives in the same namespace as the Certificate resource.

Defines annotations and labels to be copied to the Certificate’s Secret. Labels and annotations on the Secret will be changed as they appear on the SecretTemplate when added or removed. SecretTemplate annotations are added in conjunction with, and cannot overwrite, the base set of annotations cert-manager sets on the Certificate’s Secret.

Additional keystore output formats to be stored in the Certificate’s Secret.

Reference to the issuer responsible for issuing the certificate. If the issuer is namespace-scoped, it must be in the same namespace as the Certificate. If the issuer is cluster-scoped, it can be used from any namespace.

The name field of the reference must always be specified.

Requested basic constraints isCA value. The isCA value is used to set the isCA field on the created CertificateRequest resources. Note that the issuer may choose to ignore the requested isCA value, just like any other requested attribute.

If true, this will automatically add the cert sign usage to the list of requested usages.

Requested key usages and extended key usages. These usages are used to set the usages field on the created CertificateRequest resources. If encodeUsagesInRequest is unset or set to true, the usages will additionally be encoded in the request field which contains the CSR blob.

If unset, defaults to digital signature and key encipherment.

Private key options. These include the key algorithm and size, the used encoding and the rotation policy.

This option defaults to true, and should only be disabled if the target issuer does not support CSRs with these X509 KeyUsage/ ExtKeyUsage extensions.

The maximum number of CertificateRequest revisions that are maintained in the Certificate’s history. Each revision represents a single CertificateRequest created by this Certificate, either when it was created, renewed, or Spec was changed. Revisions will be removed by oldest first if the number of revisions exceeds this number.

If set, revisionHistoryLimit must be a value of 1 or greater. If unset (nil), revisions will not be garbage collected. Default value is nil.

Defines extra output formats of the private key and signed certificate chain to be written to this Certificate’s target Secret.

This is an Alpha Feature and is only enabled with the --feature-gates=AdditionalCertificateOutputFormats=true option set on both the controller and webhook components.

List of status conditions to indicate the status of certificates. Known condition types are Ready and Issuing.

LastFailureTime is set only if the lastest issuance for this Certificate failed and contains the time of the failure. If an issuance has failed, the delay till the next issuance will be calculated using formula time.Hour * 2 ^ (failedIssuanceAttempts - 1). If the latest issuance has succeeded this field will be unset.

The time after which the certificate stored in the secret named by this resource in spec.secretName is valid.

The expiration time of the certificate stored in the secret named by this resource in spec.secretName.

RenewalTime is the time at which the certificate will be next renewed. If not set, no upcoming renewal is scheduled.

The current ‘revision’ of the certificate as issued.

When a CertificateRequest resource is created, it will have the cert-manager.io/certificate-revision set to one greater than the current value of this field.

Upon issuance, this field will be set to the value of the annotation on the CertificateRequest resource used to issue the certificate.

Persisting the value on the CertificateRequest resource allows the certificates controller to know whether a request is part of an old issuance or if it is part of the ongoing revision’s issuance by checking if the revision value in the annotation is greater than this field.

The name of the Secret resource containing the private key to be used for the next certificate iteration. The keymanager controller will automatically set this field if the Issuing condition is set to True. It will automatically unset this field when the Issuing condition is not set or False.

The number of continuous failed issuance attempts up till now. This field gets removed (if set) on a successful issuance and gets set to 1 if unset and an issuance has failed. If an issuance has failed, the delay till the next issuance will be calculated using formula time.Hour * 2 ^ (failedIssuanceAttempts - 1).

Type of the condition, known values are (Ready).

Status of the condition, one of (True, False, Unknown).

LastTransitionTime is the timestamp corresponding to the last status change of this condition.

Reason is a brief machine readable explanation for the condition’s last transition.

Message is a human readable description of the details of the last transition, complementing reason.

If set, this represents the .metadata.generation that the condition was set based upon. For instance, if .metadata.generation is currently 12, but the .status.condition[x].observedGeneration is 9, the condition is out of date with respect to the current state of the Issuer.

"Ready"

IssuerConditionReady represents the fact that a given Issuer condition is in ready state and able to issue certificates. If the status of this condition is False, CertificateRequest controllers should prevent attempts to sign certificates.

ACME configures this issuer to communicate with a RFC8555 (ACME) server to obtain signed x509 certificates.

CA configures this issuer to sign certificates using a signing CA keypair stored in a Secret resource. This is used to build internal PKIs that are managed by cert-manager.

When true, cert-manager will only ever query the configured DNS resolvers to perform the ACME DNS01 self check. This is useful in DNS constrained environments, where access to authoritative nameservers is restricted. Enabling this option could cause the DNS01 self check to take longer due to caching performed by the recursive nameservers.

The duration the controller should wait between a propagation check. Despite the name, this flag is used to configure the wait period for both DNS01 and HTTP01 challenge propagation checks. For DNS01 challenges the propagation check verifies that a TXT record with the challenge token has been created. For HTTP01 challenges the propagation check verifies that the challenge token is served at the challenge URL. This should be a valid duration string, for example 180s or 1h
